#2 Former WWE Divas Champion Paige (AJ Lee)
Paige's in-ring career in WWE met an unfortunate end owing to injuries, but she is still hopeful for a return, her hopes buoyed by the examples set by Daniel Bryan and Edge.
Her debut in the company was an iconic moment and the only one amongst the entries on the list to be featured in a movie, featuring as the climax for "Fighting With My Family."
Paige debuted the night following Wrestlemania 30 and won the Divas Champion from AJ Lee. It was a truly surprising moment that immediately solidified the debutant as a dangerous force.
#1 Former WWE Universal Champion Kevin Owens (John Cena)
John Cena's run with the United States Championship enhanced the title's prestige, as The Franchise Player regularly faced up-and-coming stars in championship matches.
Kevin Owens, still the NXT Champion, answered one of Cena's open challenges, disrespecting his opponent and the title. In his debut, a non-title match at Elimination Chamber, he managed to defeat the usually triumphant Cena.
While Owens ultimately did not manage to dominate Cena in their rivalry, the result of his debut match surprised most fans. Owens has been booked as a major superstar of the company ever since his debut.
